its an almost useless vaccine from a few recent reports. Costa Rica has decided to dump it completely its been so bad. I would expect more to follow from what I've seen on Reuters etc.

I wonder how many deals the Chinese got for pushing this useless vaccine via diplomacy.

It's a stretch to call it almost useless. It is certainly effective in reducing the number of intensive care admissions and deaths. The problem is mutations keep popping up before we can obtain herd immunity. The vaccines needs to be continuously updated.

I wish I could find the article I was reading a few days ago. It said something like: zero antibodies found in vaccinated until 2nd jab, then the effectiveness of the 2nd jab seems to struggle to bring it up to 50%.

I would call that nearly useless. If they are ignoring these poor statistics and just rolling back to pre-covid rules I'd say its worse than nearly useless.

50% is much, much better than 0%. Also there is a reason some vaccines need to be administered as 2 doses. It is irrelevant to mention the antibodies after the first dose.

Let's not write this off as due to a less-effective vaccine until we find out whether or not this is in line with the expected effectiveness of that vaccine.

>Kudus, which has about 5,000 healthcare workers, is battling an outbreak believed to be driven by the more transmissible Delta variant, which has raised its bed occupancy rates above 90%.

With each variant, nature gets another shot at obsoleting all existing vaccinations.

> Let's not write this off as due to a less-effective vaccine until we find out whether or not this is in line with the expected effectiveness of that vaccine.

Sinovac does not have usable effectiveness data, due to the manner and place of its development. It is well-known internationally to be less effective than many other options.

> With each variant, nature gets another shot at obsoleting all existing vaccinations.

Please don't hyperbolize. "Obsoleting all existing vaccinations" means a new disease, not a variant. And every mutation is a tradeoff: if COVID-19 "starts over", it may well be much less virulent: less transmissible, or less deadly, or both.
